The Philippines has launched a comic book to counter what the country says is China’s disinformation campaign to push its expansive territorial claims in the South China Sea.

The Philippines will soon decide on an international platform to sue China for alleged damage to the marine environment, its justice minister said, as it pursues a second high-profile legal challenge against Beijing over the South China Sea.

The United States is not a party to the issue of the South China Sea and has no right to interfere in maritime issues between China and the Philippines, Foreign Ministry spokeswoman Mao Ning said on Thursday after Washington and Manila made unwarranted remarks against Beijing.
